The pamphlet EP 0 288 097 A1 describes an attachment structure for detachably attaching an accessory to a bicycle handlebar. Such an accessory is designed as a bicycle bell, which is attached to the bicycle handlebars outside of the bicycle handlebars via a support arm.

Against this background, one task was to adapt an acoustic signaling device to external conditions.

This problem is solved by an arrangement with the features of patent claim 1 . Embodiments of the arrangement emerge from the dependent patent claims and the description.

The arrangement according to the invention is designed to generate an acoustic signal in a link arrangement, the link arrangement being designed for steering a vehicle, usually manually. The arrangement has a bell and a signal switch, the bell being arranged in an interior space of the link arrangement and enclosed by a wall of the link arrangement and the signal switch, the interior space also being enclosed by the wall and the signal switch. The signal switch, which is arranged on or in the wall, is designed to strike or act on the bell when it is usually actuated or operated manually.

The handlebar assembly may include handlebars and handlebars. Depending on the definition, the handlebar can also be designed or referred to as a handlebar and/or a handle. Depending on the definition, the steering rod can also be designed or referred to as a holding rod.

Accordingly, the signal switch is designed to hit the bell when it is usually actuated or operated manually, the bell being designed to generate the acoustic signal in the interior of the handlebar arrangement when it is hit or acted upon by the signal switch, when the signal switch is operated.

It is envisaged that the bell will at least partially, e.g. H. either partially or completely, can be arranged or accommodated in an interior of the link of the link assembly or in the link of the link assembly, wherein the interior is at least partially, d. H. either partially or completely enclosed by a wall of the handlebar and thus by the handlebar.

Alternatively or additionally, the bell can be arranged or accommodated at least partially, ie either partially or completely, in an interior space of the handlebar or in the handlebar, which is at least partially, ie either is partially or completely enclosed by a wall of the handlebar or by the handlebar.

In this case, the link can be arranged at an upper end of the handlebar or holding rod, the handlebar and the handlebar being connected to one another at a transition. In one embodiment, the bell is arranged in an interior space of the transition or in the transition, e.g. in a junction, between the handlebar and the handlebar, the interior space for receiving the bell being both a wall of the handlebar and a wall of the handlebar is enclosed.

It is provided that the wall of the handlebar arrangement, i.e. the handlebar and/or the handlebar, has several wall sections or screens or is composed or formed from several wall sections of the handlebar and/or the handlebar, the interior space for receiving the bell is enclosed by at least one wall section or at least one panel and by the signal switch as a further wall section. The signal switch is movable on the wall or on the housing or on at least one wall section or at least one further wall section, i. H. rotatable and / or tiltable, stored. The wall or the wall sections form a housing of the handlebar arrangement, for example a housing of the handlebar and/or the handlebar or the holding rod.

The at least one wall section can be made of metal or plastic. In addition, the bell can be connected to the at least one wall section in an acoustically conductive or sound-conductive manner.

The arrangement can be designed or provided for a steering arrangement for steering a scooter or a vehicle designed as a scooter. It is also possible for the arrangement to be designed for a handlebar arrangement of a vehicle designed as a bicycle. Alternatively or additionally, the arrangement for a steering arrangement for steering an electrically driven vehicle, for example. A small electric vehicle, d. H. an electric scooter or an electric bicycle.

With the arrangement presented, it is possible to integrate an acoustic signaling device into the small electric vehicle designed, for example, as a scooter.

In this case, the bell or the bell is integrated into the housing of the link or is arranged within the link arrangement, the housing being formed or composed of the at least one wall section. The signal switch as a beater for triggering the usually bright-sounding or high-sounding electrical signal is designed or designed, also optically, as part of the housing.

The bell is thus protected from the weather in the handlebar arrangement, for example in the handlebars and/or handle or grab handle of the vehicle. Unlike usual, there are no protruding metal parts. The bell is also optically integrated in the handlebar arrangement, for example in the handlebars, or within the housing. Furthermore, a number of functional parts can be kept low. In an embodiment, functional parts of the arrangement for generating the acoustic signal can be covered by the cover of the link arrangement, for example on the link, and thus by a wall of the link arrangement, with the light-sounding bell, for example, being integrated optically and functionally into the link arrangement.

The housing can have several, i. H. have at least two wall sections, e.g. shells and/or screens, which enclose the bell as a sound body. At least one wall section of the housing, like the sound body, can be made of metal. Alternatively or additionally, at least one wall section can be made of plastic.

It is also possible for the sound body and thus the bell to be connected to the at least one wall section at least temporarily when it is acted upon by the signal switch, e.g. the beater, and made to vibrate, if necessary continuously, e.g. by a sound transmission element made of metal of the housing is mechanically connected. It is thus possible to transmit and acoustically amplify the sound of the bell to the at least one wall section of the housing.

The handlebar arrangement, ie the handlebars or handle and the handlebar or handlebar, can be tubular at least in sections and have a correspondingly cylindrical cross section, with the sound body being able to be arranged in a tubular section. In addition, the handlebar or handle can be closed and/or loop-shaped and enclose an, for example, largely triangular opening. The transition of the handlebar arrangement between the handlebar and the handlebar can be designed or can be designated as a branch and/or as a fork between the handlebar and the handlebar, on which three tubular sections, namely two sections of the loop-shaped handlebar and one section the handlebar, together, for example. Y-för mig are connected or meet. In this case, the sound body can be arranged within the, for example, y-shaped branch, for example, fork, and thus in an interior space of the handlebar arrangement between the handlebar and the handlebar. Depending on the definition, the branch can be a transition from the, for example, loop-shaped closed handlebar to the handlebar, which is also tubular, with the handlebar being arranged, usually fastened, at an upper end of the handlebar.

Since the sound body is arranged within the handlebar arrangement, there is no need for the otherwise usual protruding components for providing a bell, on which a user or driver could get caught, which is why the safety of the user can be improved. In addition, the arrangement can be used to improve a design for the small vehicle, which is usually designed as a scooter. The bell arranged within the link arrangement is protected from the weather, for example from moisture, with interference with a signaling effect, for example a bright sound, of the bell being avoided.
